CONVEYER.

Application ledDecember 11, 1923. Serial No. 879,891.

more particularly to the type-knownasthe belt conveyers. The objects are to provide a conveyer which will do away with the ordina-ry belt troughing rollers, the return belt rollers and the supporting structures and bridges therefor; which will be shaped so as to take the greatest load with the least strain; which will have no parts touching the carrier to wear the same; which will require less power for its operation; which will be lighter and cheaper to manufacture and install than conveyers heretofore made, and which is adapted to carry material up a greater inclination than heretofore possible with this type of conveyers.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to .the accompanying drawings in whichy Figure 1 is a side elevation partly 1n sec-V tion of a conveyer constructed in accordance with my invention,

Figure2 is an enlarged section on line 2-2 of Figure 1,

vFigure 5 a modified form of supporting and attaching means for the carrier,

Figure 7 a fragmentary plan view of an other form of conveyer, c

Figure 8 a section on line 8-8 of Flgure 7,

Figure 9 a modified form of the conveyer shown in Figure 1 showing it as used for carrying material up a steep incline,

Figure 10 a section on line 10-10 of Flgure 9, and

Figure 11 a central section through a modied form used for long conveyers.

In the drawings, for clearness of illustration, I have shown cables supporting a carrier lbelt but any suitable chains and carrier may be substituted for the cables and belt.

Referring to the drawings, 1 indicates my improved conveyer, 2 the take-up supporting means, 3 the driving supporting means, 4 the means for feedin material to the conveyer and 5 the means or receiving material from the conveyer. The take-up supporting means may be of any suitable construction which includes wheel 6 adjustably mounted in a slotted frame 7 and held in adjusted position by means of screw mechanism shown at 8. The driving means may be of any suitable construction which includes wheels 9 connected with a train ofgearing 10v connected to a motor 11. The feeding'means may be of the usual type which includes a hopper 12, a reciprocating truck 13 mounted under the hopper to feed material 14 jonto the conveyer. The'material receiving means 5 may be of any suitablev construction which includes a hopper 15 for guiding material to a receptacle or bunker 16 or any other desired place.

My improved conveyer 1 consists of endless cables 17 mounted on the wheels 6 and 9 and having suspended therebetween an endless -carrier or belt 18. The means for suspending the carrier from the cables consist of clips 19 having one end 2O hingedto belt 18 as shown at 21, andthe other end 22 wrapped around the cable and secured thereto in any suitable manner. The clips 19 are preferably madefromispring metal so that a resilient suspension means for the belt Yis provided.

Figures 5 and 6 show modified means for suspending the belt from the cables, consisting of clips 19` having `one end 22a clamped to the cables and vthe other end 20xt hinged at 21a to one end of a strap 23. The other end of the strap extends to the othercable and is connected thereto in a similar manner. The belt 18 may be riveted to the strap at 24 or otherwise secured thereto. These straps remove the strain from the edge of the belt and thereby allow a belt or lighter weightto be used.

In Figure 3 I have shown the wheels 6a and 9a disposed at an incline to each other so that the distance between the upper runs of the cables will be less than the dista-nce between the lower runs. This position of the wheels causes the lower run of the belt 18 to stretch and extend beyond `the side edges of the upperrun, as shown 'at 25, so

l.that any material fallin rfrom the vupper l' hooking their upper edges 29 to a rod 30 secured to the belt. This arrangement may be substituted for the bucket type of conveyer used for steep inclines and has the advantage of being capable of passing through what is known as a traveling tripper which is movable along the conveyer for receiving the discharged material from. any part of the conve er and delivering it to various parts of a unker. Y

Figure 11 shows a strut 31 connected to the hinges 22 for keeping the edges of the belt-separated. The number of these struts necessary in a conveyer depends on the -length ofthe conveyer and the material conveyed.'

In use, as the material is discharged from the feeding means 4 onto belt 18, the weiglliit of the material'will cause the belt to ta e substantially the curve shown at 32 in Figure 2 which is similar to a catenary curve.

The belt being so curved yis capable of carrying the greatest load with -the least strain. As the upper run of the conveyer 1s moved upward by the drivingl means 3, cables 17 support belt 18 by the clips 19. This d oes away with the usual rollers for troughing or shaping the curvature of the belt and the rollers for supporting the lower or return run of the belt. As the conveyer passes over wheels 9 of the driving means, the material is discharged into the receiving means 5.v The belt in its lower run will take the curvature shown at 33 in Figure 2. The hinge connections 22 allow the belt to `take this natural shape without in any way straining the same. Asl the conveyer passes over the wheels 6 of the take-up means 2, the hinge y connections 22 allow the belt to swing from vthe position shown a.t.33 and take the sha e shown at 32. The belt is thus always rea y to receive material from .the feeding means, 4. Any vibrations produced on the belt during its operation are absorbed by the spring c'lips 19.

. YWhen the wheels 68L and 9a of thetake-up and driving means 2 and 3 are disposed' at an incline to each other as shown in Figure 3, the upper run of the belt as 1t passes over the wheels 9a is stretched so that vthe side edges extend beyond the side edges of the top run as shown at 25.

. jg. forth constructing' a conveyer as above set it may be manufactured and installed at a very low cost and the repairs andupkeep are reduced to a minimum.

While I have described my invention as taking a particular form, it will be'understood that the various parts may be changed without de art-ing from the s irit thereof, and hence Ido not -limit myse f to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tofsecure by Letters Patent isz- 1. A conveyer including cables; .resilient means attached to the cables, and a carrier suspended from 'the' resilient means..

2. -A conve er including cables; spring clips attache to the cables, and a carrier suspended from the clips.

3. A conveyer includin cables; spring strips having one end attac ed to the cables, and an endless carrier attached to and suspended from the other end of the strips.

4. A conveyer includin cables spring strips having one end attacedto the cables, and an endless carrier hinged to and suspended from the other end of the strips. 5. A conveyer including cables; spring strips having one end wrapped around to embrace the cables,'and an endless carrier attached to the other end of the'spring strips.v

6. A conveyer including cables; a carrier;

straps secured to the carrier, and resilient means connected with the straps and the cable.

7. A conveyer including cables; springl belt, and means forI moving the cables.

10. A conveyer including cables; a partitioned carrier spaced from the cables; suspending means secured to the cable and attached to the carrier, and means for moving the cables.

`In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. ARTHUR WARNER. Witnesses: ,l V
